BACKGROUND Tracheostomy is a standard procedure in critically ill patients requiring mechanical ventilation or airway protection for extended periods. The main cause of death is haemorrhage, most commonly owing to a trachea-to-innominate artery fistula, usually requiring surgical treatment. CASE PRESENTATION Here we report the case of an 83-yr-old woman with a subarachnoid haemorrhage, who incurred a trachea-to-innominate artery transfixion following percutaneous tracheostomy, successfully and conservatively managed by interventional radiology. CONCLUSIONS The use of peri-procedural ultrasound examination of the neck can reduce the risk of complications related to vessel anatomical variants. When the tracheostomy is complicated by bleeding, the procedure should be stopped in order to diagnose the vascular iatrogenic injury and to evaluate the best therapeutic approach by a multidisciplinary team.

在经皮气管切开术中用导丝保守治疗气管至无名动脉的穿透：一例报道。

背景技术气管切开术是需要长期进行机械通气或气道保护的重症患者的标准程序。死亡的主要原因是出血，最常见的原因是气管至无名的动脉瘘，通常需要手术治疗。病例介绍在这里，我们报道了一名83岁的蛛网膜下腔出血患者，该患者在经皮气管切开术后成功进行了气管至无创动脉穿刺术，并通过介入放射学成功地进行了保守治疗。结论：对颈部进行围手术期超声检查可以减少与血管解剖变异有关的并发症的风险。当气管切开术并发出血时，
